Abstract: Bacterioplankton community composition has become the center of research attention inrecent years. Bacteria associated with toxic cyanobacteria blooms have attracted considerable interest.However, little is known about the environmental factors driving the bacteria community, includingthe impact of invasive cyanobacteria. Therefore, our aim has been to determine the relationships be-tween heterotrophic bacteria and phytoplankton community composition across 24 Polish lakes withdifferent contributions of cyanobacteria including the invasive speciesRaphidiopsis raciborskii.Thisanalysis revealed that cyanobacteria were present in 16 lakes, whileR. raciborskiioccurred in 14 lakes.Our results show that bacteria communities differed between lakes dominated by cyanobacteria andlakes with minor contributions of cyanobacteria but did not differ between lakes withR. raciborskiiand other lakes. Physical factors, including water and Secchi depth, were the major drivers of bacteriaand phytoplankton community composition. However, in lakes dominated by cyanobacteria, bacte-rial community composition was also influenced by biotic factors such as the amount ofR. raciborskii,chlorophyll-a and total phytoplankton biomass. Thus, our study provides novel evidence on theinfluence of environmental factors andR. raciborskiion lake bacteria communities.
